Staying constantly online has never been easier with powerful smartphones and tablets, but Google's prototype heads-up display glasses goes even further with its own take on augmented reality. Dubbed Project Glass, the spectacles can stream real-time data such as location or social media connectivity to the lens, record video and take pictures - all designed for an almost hands-free experience. So in theory, you don't have to take out your phone to snap pictures or get the latest weather report, a simple voice command could do the trick. Google employees are currently field-testing the product to gauge how Project Glass performs in the real world, and they've also begun to reach to out to the masses to garner feedback on what people think about it. Watch the preview below to see how Project Glass works - so far it's a pretty seamless, unobtrusive online experience right in front of your eyes. Of course, we'll have to wait for the actual product to hit retail stores before we pass on judgement.
